具有docker compose的Jenkins在尝试连接到的docker守护程序套接字时被拒绝unix:///var/run/docker.sock

我想在我的vps上设置一些停靠的工具。包括詹金斯和一名代理人。一切正常，但在jenkins中使用docker代理时，我遇到以下错误：

+ docker build -t 286802dd81862d714cfc6a90c84d30200546eaa9 -f Dockerfile .

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.39/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&session=srtihghhshf8z9c2lkdnvr8dm&shmsize=0&t=286802dd81862d714cfc6a90c84d30200546eaa9&target=&ulimits=null&version=1: dial unix /var/run/docker.sock: connect: permission denied

下面是我的docker compose的外观：

我的撰写文件中是否缺少某些内容

到目前为止，我已经尝试将jenkins用户添加到正在运行的docker实例的docker和root组中，但没有成功。

我找到了一种解决方法。我只是在docker-compose.yml中指定了root用户，如下所示：

  jenkins:
    image: jenkinsci/blueocean:latest
    user: root
    networks:
      - mynetwork
    environment:
      - VIRTUAL_HOST=jenkins.mydomain.com
      - VIRTUAL_PORT=8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./jenkins-data:/var/jenkins_home
      - ./jenkins-docker-certs:/certs/client:ro
      - ./jenkins-home:/home
    restart: always
